President Vladimir Putin has sought to ease fears over Russia's economy, insisting that the dramatic fall in the rouble will stabilize. Speaking at his end-of-year news conference, which lasted over three hours, he blamed outside factors for the currency hitting an all-time low.But he admitted Russia's Central Bank could have acted more swiftly. Russia is on the verge of recession due to falling oil prices and sanctions over its role in the Ukraine crisis. However, the President denied pursuing an aggressive foreign policy and accused the US and EU of conspiring to weaken Russia.
